Indeed.  Meanwhile, this sort of categorization of strings can be
useful, as evidenced by the addition of String switches to Java 7.

The portable Scheme way to do this would be to use symbols instead of
strings, since ordinarily symbols are interned and thereby eqv?, but I
could see a place for Kawa-specific syntax that compiles to the
equivalent of a Java String switch block (which uses hash codes and a
lookupswitch to avoid doing every string comparison in a big if-else

I'm not sure what we would call the macro, though -- string-case makes
me think of uppercase vs lowercase.
